ABSTRACT:
Filament cables of denier above 10,000 dtex are produced by operating several continuous melt spinning-stretching processes at production speeds above 3,000 m/min, to form several continuously spun and stretched filament bundles, which bundles are then continuously plied and deposited in the form of a cable.
The process among others is useful for high speed production of filament cables of nylon-6 with improved breaking strength and/or breaking extension.
